White Paper: A Methodology for Superior Plastic Extrusion Die Design with ANSYS

Extrusion is one of the most widely used processes for polymer processing. Examples of extrusion include film, pipe, sheet, profiles, fiber and filament, wire and cable, and coatings coextrusion (see Figure 2). In each type of extrusion, the polymer is forced through a die to create the desired shape. Meeting the current and anticipated growth in demand of complex extruded shapes requires quick and accurate die design from the start. Ideally, the design of the die will minimize the process of trial and error and avoid costly shut down of production lines. Computer simulation (science) using computational fluid dynamics (CFD) can supplement existing experience (art) in the die design process by providing a cost-effective tool to investigate new design options. Moreover, coupling computational modeling with existing in-house experience facilitates the transfer of knowledge to the entire die design team and increases the range in possibilities for innovative approaches.
